Single light slowly moves across the horizon.A single light passed a group of 5 adults tonight around 8:45 pm. Moved from west to east. Was the size of a bb gun bb no strob, no sound. Not sure how high as it was night. Blinked off & on erratically, like going from the size of a bb to the size of all the other stars. Disappeared over the horizon. Object took 2-3 minutes to go from 40 degrees above my head over the horizon.Was not a plane, helicopter, or any Other flying object I've witnessed living in close proximity to a large airport.
